Ensure Re-register of metrics variables after a reload (#2080)
* - ensure plugins that use prometheus.MustRegister, re-register after reload
- removing once.Do on the startup function was simplest way to do it.
* - fix underscored names (advice of bot)
* - tune existing UT for reload, and add a test verifying failing reload does not prevent correct registering for metrics
* - ensure different ports for tests that can run in same time ..
